41 .'Ilhi'siinvention rela-tes `to floaders for revolvers of-any type-and it has for itsobject to provide animproved loaderwherein the pins adapted to retain-.and releasev the cartridges, l instead of `being rotated inahorizontal plane as in -a previous v application to be filed` as a division of application Serial No. 514,801 filed December 18, 1943, `are slidable longitudinallywithin the central cylinder of the loader bymeans-of the ,pivotal connection of the Vpins lwith a disc carriedbya longitudinal central stem `si-lojectedto theelastic tension of a coil .spring surrounding itand carrying exteriorly thereof 4.a disc adapted to receive the pressure Yof one-of the users lingers, wherebyaslight pressure "will be'suiiicientfto get thewsirnultaneous rcloading and cooling of a revolvers chambers, thereby -giving certain self-acting character to such kind of mechanisms, withoutfalteringtheir eiciency.

Another object of the invention is to provide said Yloaders with means whereby the discharge of oil or other lubricating liquid will be obtained moresafely andeciently than by mere outlet holeslin an inner vessel movable within the central cylinder as is provided in my prior application, the central cylinder being adapted to serve as an oil vessel and the oil being discharged through a seat valve governed by the central longitudinal stem carrying the pins for retaining and vreleasing the cartridges, so that upon alight pressure being exerted by'a finger to actuate the cartridge releasing mechanism, the oil valve will be opened also and the oil will beallowed tc Yfreely ilow through a wide opening in the bottom portion of the central cylinder, which opening also serves for injection of oil therethrough into the cylinder.

The inventionis described with reference to the l "gures of the accompanying drawing, 'of which:

Figure 8 i's a similar section `vievv tothat of Fig. '7, showingthel'position of the innerme'chanism for 'cartridge release in the modified form.

In Figs. l, 2, 3, 4 and "5pt 'thedrawing the numeral I indicates'the-central cylinderof the loader to which are rigidly joined by means of vertical joint Alinesvvhich can be madeby soldering, a plurality ofouter cylinders 2 all parallel to the central-cy1inder| land being of the same diameter which will preferablybe smaller than the diameter of the central cylinder I but larger than the diameter ofthe cartridges 3 so as, to be apt to "respectively'receive the latterttherein, the length of the central cylinder fl beingr at least equal-to that of the outer cylinders 2.

The outer cylinders 2 `are open-belowand have at their top portion Ya big opening "4to permit the examination Yof the percussion cap vof Veach cartridge. Thefcentral cylinder I has'athickened bottom portion A5 provided with a Wide opening 6 and :at 'its `toplportion `it has an Yenlarged extension inthe shape of `-acup l the bottom of whichis a disc' having a 'central opening 9 and which "constitutes -the top Aportion of `sliepen-trai cylinderltherebyclosing it.

Throughrtheopeningfof the disc is slidably mounted at `the axis'of the cylinder I arstem Il] carrying vvlixedly thereonfby'means of a pin II througha sleeve I'2 a cylinder I2 closed above and openbelowwhich smoothly t'sinto the central cylinder Iiandfhasits length equal to about half thelength of the central cylinder, its upper portion remainingnormally ata certain distance from the disc obturatingthe cylinder I and its lower edge remainingat about the 'same distance from the bottom 5 cfcentral cylinder I. The stem I0 has its lowerpcrtion Ill of -reduced diameter to pass loosely through the wide opening 'of'the bottom o"f central cylinder I and said lowerportionendsexteriorly 'of Vthe bottom 5 in a valve 4I3 :adapted tof'seat on the lower 'edge of the opening' "and`provided with a lower recess I 4 adapted torest on a projection usually provided at the top center of the magazine of some revolvers. lThestem 'Ihas near the upper end of the "reduced portion ri' ia 'transversal notch Idwhich'is crossed by .ashorizontal pin lhaving its ends rigidlysecured totheperipherialWall of the cylinder I beneaththe inner cylinder I2an'd said stem I 0 is surrounded between the'upper portion of the`inner`cylinder=l2 and the pin I5 Vby'a coil spring --I6 tending to maintain `the stem I 0 raised, lsovthat its'upper endwill project-,upward somewhat smallerthan the central cylinder and being provided with a number of holes corresponding to the number of outer cylinders. Through said holes are pivotally connected the inner ring-shaped ends of eye-bolts or pins I9 mounted to slide across bevelled openings 2@ formed at the joint of the peripherial wall of the central cylinder I and of each of the outer cylinders 2, the bolts I9 being sufficiently long to protrude in a position into the outer Cylinders 2 until placed beneath the flange 2I of the cartridges 3 lodged in the respective outer cylinders 2 to retain the cartridges 3 within the cylinders 2 and t remain lodged in another position within the central cylinder I.

The central cylinder I is filled with oil 23 in the space limited by the bottom 5 of the central cylinder and by a hole 25 at a middle point of the height of the inner cylinder I2, which can be made by means of an injector through the space be central cylinder I. 'The entering of outer air to permit the egress of oil 23 is effected through a hole 24 in cylinderl and an adjacent cylinder 2 and hole 25 in inner cylinder I2, which holes register one another in the position in which the cartridges 3 are released.

To discharge the loader into a revolver, the same is placed in resting position ofv recess I4 of valve I3 on theprojection usually carried 'bythe magazine of a revolver of an appropriate caliber, so that the points 22 of the cartridges will partly penetrate into the chambers of such a magazine,

and upon the user pressing with one linger the disc I'I, the stem I il will descend against the elastic tension ofthe spring Iiiythe' valve I3 thereby withdrawing from its seat, and the pins I9 are caused to sufficiently slide downward within the bevelled openings 2i! to withdraw them from the interior of the outer cylinders 2 until they free the flanges 2I of the cartridges 3 which will be released and will fall into the chambers of thecharge, a safety pin 2S may be used which is inserted across a hole in the cup 1 vabove the disc I1 or beneath same, according tothe eifect sought to be obtained. v

In Figs. 6, 7 and 8 is illustrated a modified form of the inner mechanism for operating the pins I9. In this modiiied form the central cylinder I' has its upper end closed by an upper portion I" slightly recessed toward its centre and the stem IB' is actuated against the elastic tension oi va coil spring El surrounding the stem III' between the disc 8 secured to the cylinder I' and the disc I8' carrying the pins' I9', the transversalpin' I5 4 of the former form being omitted and the notch I4 being dispensed, the valve being an inner valve instead of an outer valve, by having the shape of a plate 28 projecting transversally from the stem I0' at the upper end of the reduced section I0" of the stem III', which reduced section Ill" ends outside the bottom E in an enlargement 29 provided with a lower recess Y353 adapted to rest on a projection usually provided at the centre of the upper portion of the magazine of some revolvers.

In this case the enlargement 29 can be provided bolt 32 of sufficient length to pass across holes" with a vertical side groove 3I to facilitate the insertion into the opening 6 of the point of an injector for oil injection.

This modied form of loader is operated similarly as the one described in the first place, by pressing with one finger the upper depressed portion E" of the cylinder I', whereupon the latter descends carrying along with it the outer cylinders 2' with the cartridges 3', the stem I0' remaining immovable,`whereupo'n thel pins I9' will run upward into thecylinder l" thereby releasing the cartridges 3' which will fall into the chambers of the revolver, and by the bottom 5' withdrawing from the valve plate 28, the oil 23' will be allowed to iiow throughthe opening '6'l which never remains closed below. In the modiedform a safety positionmay be attained'by means of `a 33 in the projecting upper portion of theI cylinder I and across a hole 34 formed in the upper en'd portion of the stem III', as shown in Figs. '7 and'8.-

It is obvious that changes may be madeiin the.

. size, oil capacity and number of the outer cyl`. inders,`a s well as in the' construction details of'.T the loader, without thereby altering the essentiall character of the invention which is sucphvpals claimed hereinafter.

What I claim is: n Y 1. A loader for revolvers, comprising a hollow central Cylinder having va side wall and closed at its vtcp and at its bottom, a plurality of cartridge receiving cylinders each open at its lower end and,
